Auto-Generated Subtitles: Is It Possible with VLC?

As a content creator, you know that adding subtitles to your videos is essential for improving accessibility, reach, and engagement. But the process of manually adding subtitles can be time-consuming, tedious, and yet, still error-prone. That’s where VLC media player comes in handy – it offers a simple and efficient way to auto-generate subtitles for your videos. In this article, we’ll explore how to use VLC to auto-generate subtitles, its benefits and limitations, and how to fine-tune the results for better accuracy and readability.

What is VLC Media Player?

Firstly, let’s recap what VLC media player is. VLC is a free and open-source media player that can play most multimedia files, including videos, audio tracks, and streams, and supports various platforms, such as Windows, macOS, Linux, and mobile devices. VLC has several advanced features, including the ability to convert, stream, and screen-record media, as well as adjust the playback speed, audio and video filters, and subtitles. It’s a versatile tool that many content creators use for editing, previewing, and distributing their content.

How to auto-generate subtitles in VLC Media Player

Now, let’s dive into the main topic – how to auto-generate subtitles in VLC. Here are the steps to follow:

Step 1: Download and install VLC Media Player if you haven’t already.

Step 2: Open VLC and go to the Media menu, then click on Convert/Save (alternatively, you can use the keyboard shortcut Ctrl+R).

Step 3: In the Open Media dialog box, click on the Add button and select the video file you want to generate subtitles for.

Step 4: Click on the Convert/Save button at the bottom, which will bring up the Convert dialog box. Here, you can choose the output format and file destination, among other settings. However, for the subtitles, we’ll choose an intermediate file format that contains the audio track and timestamps.

Step 5: In the Convert dialog box, choose the “Video – H.264 + MP3 (MP4)” profile under the Profile dropdown menu. Then, click on the wrench icon next to it to access the Profile edition dialog box.

Step 6: In the Profile edition dialog box, click on the Subtitles tab. Here, you have options to extract, add, or disable subtitles, but for our purpose, we’ll choose the “Subtitle (SRT)” option under Output.

Step 7: Click on the Save button to close the profile edition box, then click on the Start button to begin the conversion process. VLC will create an SRT file that contains the timestamp and transcription of the audio track in your video.

Step 8: After the conversion is complete, go to the location where the SRT file is saved, and open it in a text editor, such as Notepad or Sublime Text. You can edit and save the SRT file if there are any errors or formatting issues.

Step 9: Finally, go back to VLC, open your video file again, and click on the Subtitle menu, then choose Add Subtitle File. Select the SRT file you’ve just created and edited, and VLC will display the subtitles on your video.

Benefits and limitations of VLC auto-generated subtitles

Now that we’ve seen how to use VLC to auto-generate subtitles, let’s explore its benefits and limitations.


– Time-saving: Instead of manually typing or dictating the subtitles, VLC can do it for you in a matter of minutes.
– Cost-effective: VLC is a free and open-source tool, which means you don’t have to pay for proprietary software or services to generate subtitles.
– Multilingual support: VLC can transcribe audio tracks in various languages, as long as they’re spoken clearly and without much background noise.
– Customizability: If you’re not satisfied with the accuracy or style of the auto-generated subtitles, you can edit and fine-tune them using a text editor or specialized software, such as Aegisub.


– Accuracy: VLC’s auto-generated subtitles are not 100% accurate, especially if there are speaker accents, dialects, or technical terms that it may not recognize.
– Formatting: VLC’s SRT files may not have the same formatting or styling as professional subtitles, such as font size, color, position, or line breaks. You may need to adjust them manually or use the subtitle settings in your video editor.
– Tone and readability: Depending on the content and context of your video, the auto-generated subtitles may not convey the right tone, emotion, or clarity. You should review and revise them accordingly to ensure they enhance your audience’s experience.

Tips to improve the quality of VLC auto-generated subtitles

To overcome some of the limitations of VLC’s auto-generated subtitles, here are some tips you can follow:

– Speak clearly and avoid speaking too fast or too softly. This ensures that VLC can transcribe your speech accurately and with minimal errors.
– Use the right microphone and recording environment. A high-quality microphone and a noise-free environment can improve the audio quality and reduce background noise or echoes.
– Proofread and edit the SRT file. Even though VLC does its best to transcribe the audio track, you may notice typos, incorrect words, or missing dialogue. You can use a spell-check tool or a text editor to correct them.
– Use subtitle editing software. If you want to add more formatting, styling, or timing to your subtitles, you can use a specialized software such as Aegisub. This gives you more control over the appearance and flow of your subtitles.
– Use subtitle translation services. If your video targets a multilingual audience, you may want to translate the subtitles into different languages. There are many subtitle translation services available, such as or Dotsub, that can do it for you accurately and quickly.


In conclusion, VLC media player is a handy tool for content creators who want to auto-generate subtitles for their videos. It’s free, efficient, and customizable, but it also has some limitations such as accuracy and formatting. By following the steps and tips outlined in this article, you can use VLC to generate high-quality subtitles that enhance your audience’s viewing experience. Remember to review and revise the subtitles before publishing them, and don’t rely solely on auto-generated subtitles, as they may not always be perfect.
